OAuth 2 is an authorization framework that enables applications to obtain limited access to user accounts on an HTTP service, such as Facebook, GitHub, and DigitalOcean. It works by delegating user authentication to the service that hosts the user account, and authorizing third-party applications to access the user account. OAuth 2 provides authorization flows for web and desktop applications, and mobile devices.

In this post we will be discussing about securing REST APIs using Spring Boot Security OAuth2 with an example.We will be implementing AuthorizationServer,ResourceServer and some REST API for different crud operations and test these APIs using Postman. Here we will be using mysql database to read user credentials instead of in-memory authentication.Also, to ease our ORM solution, we will be using spring-data and BCryptPasswordEncoder for password encoding.
